is it worth considering upgrade from Windows 7
It depends.
If you have several older peripherals (printer, scanner, sound card etc.) for which there are no Win 10 drivers, then no. If you have none, or can afford to just replace them all, fine, go ahead. You should check the hardware manufacturer's website to see if there are Win 10 drivers available.
If you have old programs that are not compatible with Win 10, then no, unless you can do without them or replace them. Most programs that work with Win 7 will work with 10 (allegedly).
If you are using Windows Media Centre - it isn't available as part of Windows 10 and will be removed during the upgrade. You won't be able to install Windows Media Centre after the upgrade.
Most computers that run Windows 7 will run Win 10, but you should run through the compatibility checker - see this explanation for example:
Can my computer run Windows 10?
